getDyna

@nmi-agro/fdm-source / fdm-calculator/src / getDyna

Variable: getDyna

const getDyna: any

Defined in: fdm-calculator/src/mineralization/dyna.ts:179

DB-backed cached version of requestDyna.

Uses withCalculationCache from @nmi-agro/fdm-core to persist results in the FDM database. The cache key is derived from a hash of the input (excluding nmiApiKey which is redacted). The cache is automatically invalidated when the request body changes (e.g. when soil data, cultivations, or fertilizer applications are updated) or when the package version changes.

Because the DYNA model simulates the full rotation, a single cached result covers all years in the rotation. The caller should filter the returned calculationDyna array to the target calendar year before displaying.

Signature: (fdm: FdmType, input: DynaComputeInput) => Promise<DynaResult>

Cache parameters:

Function name: "requestDyna"
Version: pkg.calculatorVersion (invalidates on package upgrades)
Sensitive keys: ["nmiApiKey"] (redacted from cache key hash)

Example

import { getDyna } from "@nmi-agro/fdm-calculator"

const result = await getDyna(fdm, {
  b_id: "field_abc",
  nmiApiKey: env.NMI_API_KEY,
  requestBody: buildDynaRequest(
    field, soilData, cultivations, fertilizers,
    "arable", timeframe, cropProperties
  ),
})
// Filter to current year before rendering:
const yearData = result.calculationDyna.filter(
  d => new Date(d.b_date_calculation).getFullYear() === 2026
)
